Let's Learn Korean - Possession Particle (에게, 께, 한테서, 에게서) -

1. 에게

이미 내 목숨을 너에게 건네버린 난..
모든 의미를 너에게 맞춰버린 난..

this particle has the same meaning and usefulness with 한테. the only thing that makes them different is this particle is used for formal statement and usually to be used in written communication.

Example:  이 선물을 재진 오빠에게 드리겠습니다 = i'll give this present to Jaejin oppa

드리겠습니다 (습니다) is one of the sign that this statement is in formal form. that's why, we have to use 에게 instead of 한테.

2. 께

아픔은 없죠 이젠 그댈 나 지킬께 for you..

this particle is one level higher than 에게 although the meaning and the usefulness is the same. this particle is usually used to the very formal conversation. when the object is someone that you honour of. 

Example:  -  미나리가 양승호님께 케이크를 드렸습니다 = Minari gave the cake to Mr. Yang Seung Ho

3. 한테서, 에게서

그리워하겠죠 단 하루 한 순간도 나에게서 너무도 멀어진 너 ..

both of these particles mean 'from'. 한테서 is informal form, while 에게서 is formal form.

Example:  - 윤호 오빠한테서 고맙지를 받았어요 = I got a thank you from Yunho oppa

                  - 아버지에게서 전화를 기다립니다 = I'm waiting a call from my father


see that the second example is in formal form cause it's using honour form (읍)니다 --- 기다립니다
